Municipal By-Laws

Speed limit

In summer 2020, after public requests and an in-house survey, the municipal council voted to lower the speed limit from 50 km/h to 40 km/h on all local residential streets.
Applicable standards

In practical terms, this means that the speed limits are now as follows:

  • 30 km/h: School zones, around parks and hospitals and on routes that offer a panoramic view of the Rivière Châteauguay – namely, Boulevard D’Youville, Boulevard Salaberry Nord and Sud, and Chemin de la Haute-Rivière to Rue Primeau
  • 40 km/h: Residential streets and certain side streets
  • 50 km/h or over: Boulevards and main arteries

The purpose of this speed reduction measure is to:

  • Reduce the risk of fatal accidents and the severity of injury for the most vulnerable road users, such as pedestrians and cyclists of all ages, young children and people with reduced mobility, as the likelihood of death for a pedestrian struck by a vehicle travelling at 50 km/h is 70% while it is only 25% for a vehicle travelling at 40 km/h.
  • Increase the public’s sense of security.
  • Reduce the nuisance of road noise.
  • To report any problem related to traffic or road safety, such as people driving through stop signs or failing to comply with the speed limit, you can contact the Service de police in one of these ways:

An administrative codification is a document that combines the original text of a by-law with all the amendments made since its adoption. It has no legal weight. It is rather a tool created solely to make it easier to read and understand the by-law as a whole. Only the original by-law and its amending by-laws have legal weight.
